Can anyone tell me why the append (Desktop Management) function is not working on my 64 bit Windows 7 machine with ArcGIS 10.2.2 under the specific conditions described below? All tests on my machine were run with Windows 7 10.2.2, except for one test specified below. Other machines used Windows 7 and 10.1 or 10.2.2 I am unsure if the other machines were 64 or 32 bit.

The specific conditions are:

When the append function is run with two shapefiles, one named sites_p, the append tool runs successfully, but no records are appended to sites_p. If I rename it to sites_u, sites_t, or anything else, records are appended. This error only happens when sites_p is selected in ArcMap using the dropdown selector in the Append tool. If I add sites_p as the target dataset by selecting the filepath in ArcMap, the append function works. It also works correctly when run from ArcCatalog

The append tool was re-run after each of the steps described below. None of the steps resolved the issue:

The shapefiles were moved to a directory 1 level below my C drive with no success. All the field types and widths were checked. A blank .mxd file with only the two shapefiles was used. A new sites_p shapefile was created and tested. .net 3.5 was re-installed. I performed a clean uninstall/re-install as directed by ESRI tech support. As part of the uninstall, I also removed 64 bit background processing. All tests were repeated after the re-install

The append tool works correctly when:

It is run on other machines with the sites_p shapefile. The sites_p shapefile is converted to a file geodatabase named sites_p. It is run with ArcMap 10.2.2 and the sites_p shapefile from Microsoft Windows Technical Preview on a separate partition of my hard drive.

  • Sorry for the confusion. Can anyone tell me why the append function is not working under the specific conditions listed above? Or has anyone had similar name specific issues?

    Please just reformat the original (hit edit) into a single question.

  • In what OS environment are you running each of these tests? (please edit the question)
